How do you create balanced chemical equations?
Ex.
1. CaCO3(s) + CH3CO2H(aq) =
2. CaCO3(S) + NaHCO3(aq) =
3. Zn(s) + CH3CO2H(aq)=

* the numbers are subscripts btw

aaronq · Answer

you need to know what kind of reaction is going on (which you identify by the reactants).

I honestly don't even know where to begin. I was just told to complete this worksheet full of these equations. We never went over these.

aaronq · Answer

thats unfortunate. I would google each of the these
i can help you with the first one:

CaCO3(s) + CH3CO2H(aq) -> salt + water  ...+ CO2 (because of the carbonate)
^base              ^acid

Thank you. Is it possible for all of them to have no reaction?

aaronq · Answer

the 2nd might, the 3rd will have a reaction

it's Zn metal + acid

anonymous · Answer

Alright. I'll try to make a sense out of it. Thank you for your help.

aaronq · Answer

no problem. Check your book, these reactions are very common
